I used to get cravings immediately pre-period, usually for very salty or sugary food. Now I am right off sweet food and not that into food full stop.
My only serious full-blown craving is for gherkins, which I have had all my life, but for some reason was especially bad in my 20s, to the point where I would get up and drive to an all-night supermarket to buy a jar, and would then eat the entire jar while sitting in the car park. Funny thing is I haven't had it since becoming peri-menopausal.
Any idea what your body is missing when it craves gherkins?
